To @ZZ whom. t may concern.'

lie it known that i, (l'r'ro Vliinuiian'iu head engineer, citizen of the State of Prussia, residing at Berliinin the State of Prussia, Germany, have invented certain new and useful Improvements in Tipping Trucks, of izfliich the following is a spccifration This invention relates to a rearwardly discharging tipping truck with swinging winches and inl accordance with this in. vention a rack winch is attached to each side ofi-the truck insuch a manner that the Y* rack and its shell may'swing uponcthe axle ot the driving cog-wheel orypinion,.the arrangement being such that Veach rack winch may also be turned into a. horizontal or nearly horizontal position and may be secured in this position to the Vtruck vwhen not employed or'tpping the truck body or returning the body after the tipping operation.

rlhe invention, in its 'form at present preferred, has the upper end of each rack,

the so-called rack head, directly connected with the frame of the tipping body in a manner allowing turning or swinging of the racks in vertical planes, and has the axle or the joint or each rack head so constructed that, aft-er the body has moved backinto its normal position and is again supported by the truck frame, the racks may be swung into horizontal or approximately horizontal position with their casings by coi'ltiiuiingrotating the crank provided for the actuation of the movable parts' of the structure.

chassis) are made to lie in the same axis of rotation. Y .Y

f The effect of this varrangement, is that by continuing therotation of the crank after the body has re-assumed its normal position the rack winches are turned into horizontal position in which they thenv are secured by special means provided for this'purpose.

In order to more clearly describe my invention I refer to the accompanying drawing,fin.which\similar numbers of reference denote similar parts, and in which Figure l is a side view of the rear portion of La tipping truck constructed according to this invention, the body being shown in tipping position, Figure 2 showsthentipped body seen in the direction from the front to the rear, together with some parts-of the chassis of the truck, and Figure 3 is a detail vieW showing the body in' its normal position on the chassis. f n Y There are twoiracl winches, only one of which' will be described *sinceL the other is 'of the. same construction.

The rack 1 of the rack. winch isv guided in aV shellror casing 'which is hinged at 2 to the chassis of the truck. The. rackll has a head-` 4 which .is

hinged at 5 to `thebottom structure; of the` body. The raclcmeshes with agearing 7 which may be actuated by a crank (not shown) aiixed to the shaft 6.- VBy turning the crank in the one or the other direction' the gearing lifts or lowers the racks together with the body. Each rack and its' shell are, of course, always in the same line and when having arrived in the position of rest, each rack with its shell may be turned. into hori- PATaNr-orricn Specification of Letters Eatent.

zontal position, in which the parts are held i by a rotary locking member 8 which engages alug 9 provided at the lower end of the shellB. l/Vhen disengaging ythe parts 8 and 9 the respective rack and its shell swing down into vertical position which is possible because of the ulcrums of these parts lying in the same axialline, as above described.

Having now described my invention, what` J I desire vto ,secure by a patent 'of the United Statesis:

l. ,In a tippingitruck, the combination of a chassis; a body pivotallyfmountedlon the chassis; means for tipping the body com- I' prisinga` rackpivoted on the body; and a guideior the rack pivotally mounted on lthe chassis, the axis ofpivotalimovement of the"v guide coinciding with the j axis of pivotal movement of the rack when the body is in normal chassis. i. Y

2. In a tipping truck, .the combination Vof a chassis a 'body Vpivotally mounted on the chassis;` means for tipping the'body com- 1 prising a rack pivoted on the body and an position' supported directly by the operating pinion mounted on the chassis and engaging the rack; and al guide for the rackl Vpivotally mounted on the chassis, the axis rack when the body isA in normal. positionsupported directly upon the chassis, ,the op-v eration of the pinion after said bodyV is in normal position causing the rack and guide therefor to be swung into position substantially parallel with the chassis. v

3. In a tipping truck, the combination of a chassis; a body pivotally mounted on the chassis; means for tipping the body comprising a rack pivoted on the body; a` sheath for the rack pivotally mounted on the chassis, the axis of pivotal movement of the rack coinciding with the aXis of pivotal movement of the sheath when the body is in normal position supported directly by the chassis.

4. In a tipping truck, the combination of a chassis; a body pivotally mounted on the chassis means for tipping the body comprising a rack pivoted on the body and vertically disposed when in use; and al guide 'for the rack pivotally mounted on the chassis, the axis oit pivotal movement of the rack coinciding with the axis of pivotal movement of' the guide when the body is in normal position supportedby the chassis,

said coincidence of the axes permitting the rack to be swung into horizontal position; and means for holding the rack in horiz'ontal position.

5. In al tipping truck, the combination of a chassis; a body pivotally mounted on the chassis; means for tipping the body comprising a rack pivoted on the body and vertically disposed when in use; and a sheath for said rack pivotally mounted on the chassis, the axis of pivotal movement of the rack coinciding with the axis of pivotal movement of the sheath when the body is in normal position supported by the chassis, saidV coincidence ofethe axes permitting the rack and sheath to be swung into horizontal position; and means for engaging the sheath and holding the sheath and the rack it contains in horizontal position.

6. In a. tipping truck, the combination of an operating'rack and sheath therefor, said rack and sheath being vertically disposed when in use and movable to a horizontal position when not. in use; and a pivoted catch 'for holding thesheath in horizontal position.

In testimony whereof I have afiiiXed my signature.
